The Obama administration has taken the position that there are so many illegal aliens that it is folly to try to do anything about them. Their plan is to make them legal aliens rewarding the people who are here illegally at the expense of other people who are waiting to get in - people who might actually have some marketable skills that do not involve a shovel or a paper hat.
Think about that. Their argument is that there are lots of them so let’s not catch any of them. There is ample proof that law enforcement does not catch all of the bank robbers, rapists pedophiles and perpetrators of assorted other illegal acts. But that is not taken as reason that because we cannot catch criminal A we should not try to catch criminal B. Doesn’t work that way.
